Per multiple doctors and an audiologist the best way to clean your ears easily is to just use warm water while showering and direct it down your ear canal with moderate water pressure. I used an irrigator for years, just with tap water, but the possibility of too much pressure always worried me. I struggle(d) with ear wax build-up in my teens but have been wax free for 2 decades now, so long as I am diligent about cleaning my ears.
